Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a device for driving an electric vehicle.

[0002]

2. Description of the Related Art FIG. 4 is a plan view showing a mounting structure of a device for driving an electric vehicle according to the prior art, FIG. 5 is an enlarged view of an essential part taken in the direction of arrow B in FIG. 4, and FIG. It is a perspective view.

As shown in these figures, a motor 3 for driving an electric vehicle is connected to a propeller shaft 3 via a transmission 2, and a motor mount seat 13 and a rubber mount are mounted on a cross member 5 on the front side of the vehicle body. It is attached via 11. The motor 3 and the motor drive inverter 31 installed at a predetermined position in the vehicle body are connected by a power cable 12 that is routed and wired in the vehicle body. Note that 5 in FIG.
Is a side member on the front side of the vehicle body.

However, in the mounting structure for the electric vehicle driving device according to the above-mentioned prior art, it is necessary to secure a dedicated space for installing the inverter 3 in the vehicle body. Further, since a thick cable is used as the power cable 12 for supplying a large current to the motor 3, a relatively large maneuvering space is required in the vehicle body for wiring the power cable 12.

Therefore, in view of the above-mentioned prior art, the present invention provides a mounting structure for an electric vehicle driving device which can mount the motor driving inverter and the power cable without requiring a dedicated space for the installation. The task is to do.

[0006]

Means for Solving the Problems A first method for solving the above problems is described below.
The present invention is characterized in that an inverter for driving a motor is provided in a member of a vehicle body.

A second invention is characterized in that, in the first invention, a power cable connecting the motor and the inverter is wired through the member.

According to a third aspect of the present invention, in the second aspect of the invention, the power cable passes through the inside of the mounting portion of the motor to the member to reach the inside of the member, and passes through the member to the inverter. It is characterized by wiring to reach.

Therefore, according to the first aspect of the invention, since the inverter is arranged in the member, it is not necessary to secure the installation space for the inverter as in the conventional case.

According to the second or third invention,
Since the power cable is routed through the member, or through the motor mounting portion and the member, it is not necessary to secure a routing space for the power cable, which is different from the conventional one.

Embodiments of the present invention will be described below in detail with reference to the drawings. It should be noted that the same parts as those of the related art are denoted by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a partially cutaway view showing a mounting structure of an electric vehicle driving apparatus according to a first embodiment of the present invention.

As shown in FIG. 1, in the mounting structure of the electric vehicle driving apparatus according to the first embodiment, a motor driving inverter 7 is arranged in the cross member 4, and A power cable 12 for connecting to the motor 1 is inserted into the cross member 4 through a through hole 4c provided in the cross member 4 and wired so as to reach the inverter 7 through the cross member 4.

Therefore, according to the mounting structure for the electric vehicle driving apparatus of the first embodiment, since the inverter 7 is arranged in the cross member 4, the conventional installation space for the inverter can be omitted. it can. Further, since the power cable 12 is wired through the inside of the cross member 4, it is possible to omit the conventional space for arranging the power cable. Further, since it is not necessary to wire the members, it is easy to route the power cable.

FIG. 2 is a partial cutaway view of the mounting structure of the electric vehicle driving apparatus according to the second embodiment of the present invention (BB in FIG. 3).
FIG. 3 is a view taken in the direction of arrow A in FIG.

As shown in FIG. 2, in the mounting structure of the electric vehicle driving apparatus according to the second embodiment, the motor driving inverter 7 is arranged in the cross member 4 and the inverter 7 is The power cable 12 for connecting to the motor 1 is taken out from the mounting portion of the motor 1 to the cross member 4, that is, from the motor mount seat 13, and the rubber mount 1
Wiring is made so as to reach the inside of the cross member 4 through the inside of 1 and further reach the inverter 7 through the inside of the cross member 4.

Therefore, according to the mounting structure for the electric vehicle driving apparatus of the second embodiment, since the inverter 7 is arranged in the cross member 4, the conventional installation space for the inverter can be omitted. . Further, the power cable 12 is connected to the inside of the motor mount seat 13 and the rubber mount 1.
Since the wiring is carried out through the inside of 1 and the inside of the cross member 4, it is possible to omit the conventional space for arranging the power cable.

Although the inverter 7 is arranged in the horizontal portion of the cross member 4 in the first and second embodiments, the invention is not limited to this, and the inside of the inclined portions 4a, 4b of the cross member 4 and the like. Further, it may be arranged in the side member 5.

Further, in the first and second embodiments, the motor 1 is mounted so as to be occupied below the cross member 4, but conversely, the motor 1 is mounted so as to be occupied above the cross member 4 and the like. The present invention can also be applied to the case.

[0020]

As described above in detail with the embodiments of the invention, according to the present invention, the installation space of the inverter as in the conventional case is omitted by disposing the inverter in the member of the vehicle body. You can Further, since the power cable is routed through the inside of the member or the member and the inside of the motor mounting portion, the conventional routing space for the power cable can be substantially or completely omitted. Further, since it is not necessary to wire the members, the power cable can be easily routed.
